Embodiment 1

[0075] Such as figure 1 , figure 2 As shown, the present embodiment provides a method for evaluating and determining the direction of a railway line, comprising the following steps:

[0076] S1: build the evaluation index frame of railway line trend, described hierarchical framework comprises three stages, first-level index, second-level index and third-level index: described three stages are decision-making design stage, construction stage and operation and maintenance stage respectively; The first-level indicators include technical feasibility, economic rationality, environmental impact, social benefits and impact; the second-level indicators include line conditions, engineering conditions, operating conditions, engineering economy, natural ecological environment impact, topographic and geological conditions, social benefits and social impact ;

[0077] The line conditions include line length, minimum curve radius, bridge-tunnel ratio, maximum slope (restricted slope), to...

Abstract

The invention relates to the field of railway engineering construction, in particular to a railway line trend evaluation determination method. The invention provides a railway line trend evaluation determination method, and provides a railway line trend scheme comprehensive evaluation index system and a scheme evaluation determination method which comprehensively consider that railway constructionis in different stages and comprises four first-level indexes, eight second-level indexes and 42 third-level indexes. The problems that in the prior art, index selection is not comprehensive enough,or part of indexes are not practical and poor in operability, the development requirement of railway lines cannot be met, and the development objectives of technology, economy, environment, society and the like of railway construction at different stages cannot be reflected are effectively solved.

Description

technical field [0001] The invention relates to the field of railway engineering construction, in particular to a method for evaluating and determining the direction of a railway line. Background technique [0002] The choice of railway line will affect the size of the entire project cost, the quality of subsequent operation conditions, and at the same time have a direct impact on the ecological environment and social benefits around the line. How to obtain a more scientific and reasonable railway alignment plan among various railway alignments has important theoretical and practical significance for the sustainable development of my country's economy, environment, and society. [0003] In the existing technology, the determination of the railway line direction scheme mainly relies on the selection of a series of evaluation indicators by experts, and then determines through qualitative analysis. The evaluation indicators selected by different experts may be different, and ev...
